Abstract
This paper designs a general equilibrium model with a public sector which builds up public infrastructure. Public consumption expenditure is necessary for an efficient use of public physical capital, so there exists a productive effect for such type of public spending. The normative results derived from this framework are then confronted to the standard non-productive public consumption model. Under the assumption of efficient public consumption, the percentage of total public expenditure that must be allocated to consumption is strictly positive. This optimal percentage is obtained from the equilibrium between two opposite effects led by public consumption on public physical capital: a positive efficiency effect and a negative crowding-out effect.
